Projective content, (not-)at-issueness, information structure, and the common ground

Panel hosted at the International Pragmatics Conference 2027 (IPC20) in Helsinki 27 June–2 July 2027

Call for Abstracts

The panel seeks to advance our understanding of the nature of information that is ‘taken for granted’ in an utterance. Linguistic phenomena related to such information, most prominently presuppositions and conventional implicatures, received different analyses, e.g. as projective or not-at-issue content. Current debates center around the questions (i) whether a single analysis can capture all characteristics of this heterogenous set of phenomena; (ii) how they connect to information-structural distinctions like focus-background or topic-comment; and (iii) how such information enters and is represented in common ground. To address these questions, the panel aims at bringing together researchers from different theoretical camps with the growing field of experimental pragmatics.  

Potts (2005) analyzed conventional implicatures, e.g., the content expressed by parentheticals, appositives and expressives, as not-at-issue, drawing a distinction between the asserted proposition (at-issue content), which is typically taken to be an answer to a question under discussion (e.g. Roberts, 1996/2012; Tonhauser, 2012; but see Koev (2018) for different conceptions), and a range of other entailments and presuppositions conveyed in an utterance (not-at-issue content). Since Potts’ seminal work, characterising the difference between at-issue and not-at-issue content sparked great interest in theoretical as well as experimental research (e.g. Tonhauser, 2012; Murray, 2014; Stevens et al., 2017; Stolterfoht, 2026). One line of research drew connections between projective content and not-at-issueness, stating that diverse phenomena can be subsumed under the premise that they all project because they do not contribute at-issue content themselves but rather serve as its background (e.g. Roberts et al., 2009; Simons et al., 2010). Despite this uniformity, recent experimental findings highlighted variability and gradience in at-issueness and projection (e.g. Tonhauser, 2018; Barnes & Ebert, 2023). Only recently, research focused on factors determining the observed variability by systematically testing the influence and interplay of lexical meaning, prior beliefs and at-issueness (e.g. Degen & Tonhauser, 2025). Moreover, first attempts have been made to implement the effects of such factors in probabilistic pragmatic models (Scontras & Tonhauser, 2025). Another important desideratum is a model of how different types of content are processed incrementally (e.g. by introducing a second processing stage linked to a second layer of meaning designated to not-at-issue content; e.g. Axel-Tober et al., 2024; Czypionka et al., 2025), and also how the incremental left-to-right nature of language processing affects core properties of projection (e.g. asymmetric filtering; Mandelkern, et al., 2020; Kalomoiros & Schwarz, 2024; Tonhauser & Degen, to appear).

To shed further light on the issues sketched above, we invite contributions related to topics such as:

  • Links between (not-)at-issueness, projection, and information structural concepts, and their representation in common ground
  • Factors influencing the processing of projective or not-at-issue content
  • Theoretical and empirical approaches to the gradience of at-issueness
  • Differences/similarities of (conventional) implicatures and presuppositions
